Answer:

no because 55 is not within 34.2 - 37.8

Step-by-step explanation:

if you use this proportion:

.2/1 = x/180

x = 36

you will see that, proportionally, 36mg is for a 180-lb person

±5% of 36 is 1.8

add 1.8 to 36 to get 37.8mg

or subtract 1.8 from 36 to get 34.2

55 is not within that range
